DANGER-SIGNAL.

Specification of Letters iatent. Patented Apr. 8,1919.

Application filed October 29. 191$. Serial No. 260,132.

To all whom it may concern:

Be it known that I, NOAH A. AREL, a citizen of the United States,residing at Tulsa, in the county of Tulsa and State of Oklahoma, haveinvented I provements in Danger-Signals, of which the following is aspecification.

This invention relates to automatic signals for railroad crossings andthe like and the principal object of the invention is to providemechanical means operated'by the train for displaying a signal at thecrossing to indicate that a train is coming.

Another object of the inventlon is to provide a device of thischaracterwhich is simple and durable in construction, reliable andefficient in operation and one which can be manufactured and placed uponthe market at a minimum cost.

The invention also consists in certain other;

features of construction and in the combination and arrangement of theseveral parts,

to be hereinafter fully described, illustrated in the accompanyingdrawings and specifically pointed out in the appended claim.

In describing my invention in detail, ref-' erence will be had to theaccompaying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a plan view of my invention.

Fig. 2 is a side view with parts in section.

Figs. 3 and 4 are detailed views.

Fig. 5 is a cross section through the'upright and shaft showing themeans for hold in the parts in inoperative position.

11 these views 1 indicates the track and 2 the crossing. Adjacent thecrossing I locate an upright 3 suitably supported on a base 4:- Theupright 3 is of tubular form and the shaft 5 passes therethrough. Theend of the shaft is provided with a crank 6 and its upper end projectsabove the upright and has secured thereon an arm 7 .which contains the Ilegend Stop-Danger or similar words. A pair of shields 8 is also securedto said shaft at its upper end and a lamp '9 is placed between saidshields and is suitably secured to the upright 3. A wheel 10 isrotatably mounted at the upper end of the upright 3. This wheelissupplied with ball bearings so that it will revolve by its ownmomentum after being is engaged by the dog 12 carried by'the new andusefullmstrikers 13 which are adapted tocontact with a bell 14 carriedby the upright; The up-I right may be braced by the ladders 15. I

The crank 6 is connected with a pairof I shaft. The: wheel also carriesanumber of chains-,pass'over the guiding rollers 18. The

Eachrod is connected with an oscillating member 19, wh1ch 1s pivoted"intermediate its ends at a suitable point along the track so that ltWlllbe struck by a part carried by thetrain. Thiswill cause the rodto slideand through means of the chain 17 will partially rotate the crank andthus turn the shaft so as to place the words on the arm in rods 16 aresuitably mounted along the track and extend in opposite directions. I 7

a position where theyomay be seen by any one passingalong the crossing2. Atlthe same'time the dog engaging the rack will spln the wheel 10 andthus sound the alarm.

The shields 8 will be moved so'as to expose of. the Weighted arms 20connected with the chains and the'weight 21 connected with the roller.It will beseenthat one rod will not the lamb. so that a signal may begiven at- I mght. The parts are returned to. normal position after. thetrain has passed by means arm 6. This weight 21 is connected with thearm by a cable which passes-overasuitable v interfere with the other asthe chains will simply slack while one rod is being moved. It isthoughtfrom' the. foregoing descrip tion that the advantages andnovelfeatures of my. invention will be readily apparent.

I" desire it to be understood that I may. ,make' changes in theconstruction and in the combination and arrangement of the severalparts, provided that such changes fall within the scope of theappendedclaim. a hat I claim is; V

A device of the class described comprising an upright, a shaft rotatablysupported thereby. signal means carried by the'shaft, a wheel rotatablycarried by ,the' upright,

strikers on'said wheel, an annular rack "on said .wheel, a dog on theshaft engaging said rack, a bell on the upright adapted to be en gagedby the strikers, a trip 'ldevice located adjacent the track and adaptedto be struck by partofthe train and means forconne'ct; 1 ing said;device with theshaft. started. The wheel 7 is provided with the annularrack 11 which In testimony whereof I affix my signaturei NOAH A. ABEL. j
